Co2injection in fridge???

the cooling system for the fridge is a sealed system. So it would just keep recirulate the air thats in the fridge.

My thought is if I cut out the bottom of the freezer and seperate the fridge and freezer with a sealed piece of glass.
exaust the heat out the freezer. From what i read this will keep most of heat out of fridge. I would plug the fridge into
a lux pro dig. thermastat. This t- stat plugs into a rec. and has a rec. in the face.

the fridge would have no ventilation just co2 injection. the t-stat would cut the fridge on when the temps got above 85 and off at say 75 degrees.

i do not think the fride would run that much
Why would this not work?

if i go with the co2 i will def get 1 of the 300.00 controlers. Just wish they wasn't so much.
I'm not mister money bags but i think the return on my investment would be worth the money.
do you use co2? does anybody? use some help on which produts to buy. name brands that are junk.
name brands that are inexpensive and reliable.

i have used co2 but have switched to a dif source of carbon it is called flourish excel you can find it at you pet store and here is how you fig out your co2 without the controller but if you have the money fuck it its a cool toy
If you increase the amount
of CO​
2 to 0.2% of your rooms atmosphere, that is 2000 ppm. The first thing you need to do is figure out
how much CO
2 you need to release to bring your grow room to 2000 ppm. To do this determine the
volume of your room (length x width x height). You then multiply your room volume by 0.002 (that is
0.2%: if you want 1500 ppm that is 0.0015% multiply your room volume by 0.0015). For example, if

your room is 5 feet by 5 feet by 8 feet, your volume is 175 cubic feet (5x5x8=175) and 175 x 0.002 is
0.35. You need to release 0.35 cubic feet of CO​
2 into the room. Step two, in order to figure out how long
the valve should be open the number of cubic feet of gas required (0.35) is divided by the flow rate. If
the flow rate is 10 cubic feet per hour divide 0.35 by 10 = 0.035 hours or (0.035x60min/hour) 2.1
minutes an hour (two minutes) That is not a lot of CO
2 for a potential doubling of yields. Many timers
don’t regulate below 5 minutes (see:
Timers ) but you could start off having the valve open for 5 min.
every hour and then increase or decrease the amount of CO
2 until you see no more increases or reduced
growth. As you know by now, giving your plants too much CO
2 will not increase growth. You should
keep the room sealed as best as possible when the plants are being given CO
2. Carbon Dioxide is not
toxic to plants, so if you can’t be exact, err on the side of too much. In humans, symptoms of high or
prolonged exposure to carbon dioxide include headache, increased heart rate, dizziness, fatigue, rapid
breathing, visual and hearing dysfunctions. Exposure to higher levels may cause unconsciousness or
death within minutes of exposure. Sound scary? High levels for humans are above 2%, while what I am
describing for your plants, a large increase in yields with CO
2 at 0.2%, is not even close. Carbon dioxide

poses no real danger to you.

now that i think about with how small a frigde is and how air tight it is a controler is probly the way to go if you insist on co2 gas its not goin to take much so a timer wouldnt realy do the job for you as it would in a vented room i think its going to take a controller or a alot of trial and error

i appericiate the info on the co2. Since i'm starting slow I will not use the co2 right off. Will not use the fridge cooling system either.
What i was worried about was the heat in the sealed room. I have read that otimal temp for co2 is 85 - 90 degrees. I dont se,e me having
any trouble keeping that temp with just a intake or passive intake and exaust. Incorporate the co2 controller and dig. tsat i alredy have at a leter date.
I am a process electrician by trade in a large industrial plant. Anything is possible and free equipment. it would not be impossibe for me to run across a free super high dollar co2 monitor, ph meter, humidastat,contactor ,and any relay or timer you could think of. I have been collecting lights for years just never had the place to use them. Over 15 brand new HId fixtures of various types and loads of flouros the good ones.

I have grown outdoors ninja style for years and become very good at it. No trouble cloning or producing max yield, even have breeded with success. new to forums though so bare with me while i get my ducks in row. I will be posting pics and start my own journal soon.

thanks again for looking at my post.

I also have a micro nightstand DWC and LSting. Trail and error is the only way to learn. expeience breeds success. Any one can read a book thats the easy part. Fully automated 400w hps fridge with co2 supplimentation is what will happen. Growing the best strains in the world in the best enviroment possible. Thats what I dream of these days.:peace:
